I am hoping to move to a bungalow but yesterday i noticed the ceiling on one side was bellowing slightly my friend who is a builder said that when they didi the extension the joists have not met correctly causing the ceiling line to dip slightly could this become a problem. The bungalow had the extension 10 years ago

janett,
"could this become a problem" short answer - YES.
Needs investigating to establish exact cause and remedy.
